Frequently Asked Questions

What is Vagus Nerve Stimulation?

Vagus nerve stimulation sends electrical signals along a nerve, called the vagus nerve, parts of which run through the neck to the brain. For many years, implantable vagus nerve stimulation has been used to treat various disorders, such as epilepsy and depression, in thousands of patients.1 Click here to watch a video about vagus nerve stimulation and how it may help treat headache disorders.

How does it work in Migraine & Cluster Headaches?

It is not certain how vagus nerve stimulation treats and prevents migraines and cluster headaches, but data suggest that it may work by sending signals into the brain that reduce the amount of a substance, called glutamate, that has been associated with headache symptoms.2 Click here to watch a video about vagus nerve stimulation and how it may help headache disorders.

What is gammaCore?

The gammaCore therapy is administered with a non-invasive hand held device that produces a mild electrical signal that is transmitted to the vagus nerve through the skin.

Why Use gammaCore?

The gammaCore therapy provides a safe and effective non-invasive treatment for migraines, cluster, and some other headaches, without the side effects associated with drugs. The device is portable and easy to use. It can easily be incorporated into your daily routine.

How do I use it?

gammaCore is administered with a hand-held device, about the size of a mobile phone that generates a unique electrical signal. A conductive gel is applied on the stimulation surfaces of the device and it is placed on the neck. Each dose takes approximately 2 minutes to administer (you may require more than one dose per treatment).

What are the possible side effects?

Sometimes, you may experience hoarseness, shortness of breath, or change in voice during treatment. A tingling/pricking feeling where the device is applied is normal, but should not cause major discomfort. These effects usually stop right away once the treatment is completed.

Who cannot use it?

gammaCore should not be used by people with an implanted device such as a pacemaker, hearing aid implant, or any implanted electronic device. It should not be used in people who are diagnosed with narrowing of the arteries (carotid atherosclerosis) or those who have had surgery to cut the vagus nerve in your neck. Your doctor will help you decide if the treatment is right for you. For full prescribing information, refer to the gammaCore Instructions for Use.

What should I expect?

Results vary from person to person. You may experience immediate relief if you use gammaCore right when your symptoms or headache starts. If you use the device several times a day as a preventative therapy, you may also notice a decrease in the severity, duration, and frequency of headaches. It is possible that you may be able to reduce or eliminate the use of your headache medications when treating with gammaCore. Your doctor will help determine the best course of treatment for you.

In order to determine if you are a responder to gammaCore, an adequate trial is important. Most patients, when trained on the proper use of the device, will see a response within 3–5 acute attacks, and/or 4–8 weeks if using gammaCore as a preventative therapy. Training with a gammaCore consultant, following up with your doctor and maintaining a headache diary will give you the best opportunity to determine if you are a responder to the therapy.

Where can I get more information about gammaCore?
